In a post-apocalyptic world, society has devolved into small, warring factions. The most feared of these groups are the Smoke Junkies, a band of ruthless scavengers known for their addiction to the toxic fumes of burning scrap metal. They roam the wasteland in their battle vehicles, hulking machines cobbled together from twisted metal and salvaged parts. These crude, but deadly vehicles are their pride and joy, and the smoke junkies will stop at nothing to defend them from rival gangs.
